Abstract

Procedeul, conform inventiei, se refera la o prelucrare a concentratelor de sulfuri complexe, prajite preliminar, prin lesierea cu solutie de acid sulfuric în doua trepte, rezultând solutii din care zincul si fierul se separa sub forma de sulfati anhidri prin acidulare cu acid sulfuric concentrat. Din sulfatii rezultati separarea elementelor respective se face sub forma de oxizi sau sub forma elementara, eliminându-se astfel unele faze de purificare greu de realizat.
